I gifted a few bucks to the humble bundle, billing error meant I bought 2 extra copies that I didn't want. After emailing them saying I didn't want a refund, but to give it all to charity they kindly sent me some giftable links instead. I gave away some and I'm left with 1 which I thought I would trade.

It contains all of ze games, extras included. If anybody has any thing to trade willing to send it your way failing that, I will just get the lass to claim it and put the keys up on free games thread.
